Fermentasi Bioetanol Dari Nira Nipah Kental Secara Semi Sinambung Dengan Penambahan Ergosterol

---

The aim of the research was to obtain the best concentration of ergosterol supplemented in a very high gravity fed batch fermentation of bioetanol form Nypa sap. Tween80 and ergosterol play a role as surfactant and nutrition for Saccharomyces cerevisiae to produce ethanol on very high gravity fed batch fermentation from Nypa sap. The exploration research used four treatments with duplicate measurements. Treatments consist of E0 (ergosterol 0 mg/l), E1 (ergosterol 18 mg/l), E2 (ergosterol 24 mg/l), and E3 (ergosterol 30 mg/l). Observation was conducted every 24 hours to : sugar concentration, total cell, ethanol concentration, and pH. The best combination treatment was E1 (Tween80 0.2%; sugar 250 g/l and ergosterol 18 mg/l) which produced ethanol 17,57%.
